We compare the effects of spherical aberration on the penetration depth of single-photon and two-photon excitation for instances in which the aberration is caused by the refractive-index mismatch when a beam is focused through an interface. It is shown both theoretically and experimentally that two-photon fluorescence imaging experiences less spherical aberration and can thus propagate to a deeper depth within a thick medium.

The objective of this study was to profile trauma related psychiatric symptoms in a group of refugees not seeking mental health services and to consider the services implications. The study involved research assessments of two groups of Bosnian refugees: those who have not presented for mental health services and those who have. A total of 28 of 41 nonpresenters (70%) met symptom criteria for posttraumatic stress disorder (PTSD) diagnosis. All service presenters (N = 29) met symptom criteria for PTSD diagnosis. The group that did not present for services reported substantial but lower trauma exposure, PTSD symptom severity, and depression symptom severity. They had significant differences on all subscales of the MOS SF-36, indicating better health status. We concluded that those who do not seek services have substantial symptom levels, but their self-concept appears to be less oriented toward illness and help seeking. Innovative access, engagement, and preventive interventions are needed to address those who have symptoms but do not readily seek help for trauma mental health services.

Lelo, S.: Revised inventory of the butterflies of Bosnia and Herzegovina (Insecta: Lepidoptera: Hesperioidea, Papilionidea). Nat. Croat., Vol. 9, No. 2., 139–156, 2000, Zagreb. This work presents a third revision of the inventory of butterflies of Bosnia and Herzegovina according to the Karsholt – Razowski system. The revision was carried out from analysis of the scientific literature and published field observations from B-H. The presence of L. reali (Reissinger, 1989) has been verified personally by the author in the course of his own field research and subsequent laboratory investigations.

Este artigo tem como objetivo tracar um balanco da historiografia que aborda a tematica feminina, em suas varias vertentes: do marxismo, passando pela historia social ate os estudos de genero, em um periodo que vai dos anos 70 ate os anos 90, no Brasil.

About 10 years ago in the US, an automotive OEM consortium formed the Oxygenated Fuels Task Force which in turn created the SAE Cooperative Research Project Group 2 to develop a simple rational method for qualifying materials. At that time the focus was Methanol/ Gasoline blends. This work resulted in SAE J1681, Gasoline/Methanol Mixtures for Materials Testing. Recently this document was rewritten to make it the single, worldwide, generic source for fuel system test fluids. The paper will describe the rationale for selecting the fuel surrogate fluids and why this new SAE standard should replace all existing test fuel or test fluid standards for fuel system materials testing.
